ARTIFICIAL-STONE COMPOSITION.

Specification of Letters Patent.

PatentedAug. 4, 1914.

Application filed October 5,1912. Serial No. 724,064.

To all whom it may concern Be it known that I, W'iLLIAM Hnsnor, acitizen of the United States,and a resident of J ohnstown, in the countyof Oambria and State of Pennsylvania,have invented a new and ImprovedArtificial-Stone Composition, of which the following is" aifull, clear,and exact description.

This invention relatesto improvements in compounds that are used as abuilding, paving or facing material, in any form andsize, and consistsof a body material, sulfur and pine tar. a

The body material to be used in connec- ,tion with the sulfur and pinetar maybe gravel, sand, clay, limestone, rock, or any other similarmaterial, preferably pulverized or reduced to small particles. The bodymaterial can be used separately with the sulfur and pine tar ortogether, and it depends on the purpose for which the, material is to beused,1that is, paving, building or facing, the materials are used alltogether when a ceramic eifect is desired.

WVhen the body material has been reduced to the proper state, theproperamount of sulfur and pine tar is added, and the mixture so formedisheated to a; proper temperature, care being taken that :duringtheprocess of heating the compound is entirely mixed, so as to form ahomogeneous body. a The function of the pine tar in the com-y pound istointerbIend theparticles consti-I tuting: the body element and to giveelasticity to the so-formed'compound, while the addition ofsulfur to thecompound increases 1ts bmding quallties, and also increases 1tshardness. I"

The proportions I would preferably use are: 85 percent. ofbody material,6 per cent. of sulfur and 9 per cent. of pinetar,

but a slight modification in the percentage i of the elements formingthe compound may be made so as to give moreor less elasticity orhardness to the compound to be formedd Having thus described myinvention, 1 claim as new and desire to secure by Letters Patent:

An artificial stone composition oomprising substantially 6% of sulfur,9% of pine tar and 85% of gravel.

In testimony whereof,I1h-ave signed my name to this specification in thepresence of two subscribing witnesses.
